THRESHING-1VIACHI-N E.

Specification of Letters Patent No. 4,815, dated October 17, 1846.

tionary Thresher, and we do hereby declare the following to be a full,clear, and exact description of the construct-ion and operation of thesame, reference being had to the accompanying drawings, making a part ofthis specification, in which- Figure 1, is a perspective view of thewhole machine as a Traveling Thresher. Fig. 2, is a view of thestationary power, with a part of the connecting rod. Fig. 3, is asection of the interior construction of the cylinder 0. Fig. 4:, is asection of the interior construction of the cylinder N. Fig. 5 is anaxle that can be removed whenever the traveling thresher is to be usedas a stationary one.

In Fig. 1 A, A, are two frame pieces extending the whole length of themachine.

C, C, are two pieces outside of the hindwheels and running parallel withA A, a (Z a a, &c, are cross pieces connecting A, A, with C C, andsecured by bolts.

D, is a piece running parallel with, and between A, A.

c 0 c c, &c., are upright pieces which with the parts, described,constitutes the pincipal frame work.

B B B B are the wheels of the carriage one of which (marked B b.) hasupon its felly, an iron concave cog wheel 72,.

E E, are inclined braces in which the axles of the cylinders N and Orevolve.

F, F, are boards inclosing the machine.

G G are horizontal pieces to support tl e axles of the thresher or drum.

H, is a box to receive the sheaves.

I is a table by the side of the hopper K, also for the sheaves to belaid upon. L, the thresher or drum, the axle of which rests upon G G.

Z Z Z, &c., are crooked iron rods that pass up behind the thresher, toreceive the straw, allowing the grain to fall through, between them.

M, M, &c., are narrow pieces (not shown in the drawing,) across,underneath the thresher, wide enough apart for the grain to fallthrough, one of which has the rods Z &c., secured into it.

N, is a cylinder, having within it, several sliding rows of teeth, a a,&c., to remove the straw from the rods Z, &c., which teeth, are securedinto pieces 6 e e, &c., running the whole length, and sliding in groovesat each end of the cylinder, to and from the center sufiiciently to givethem a projection far enough in passing between the rods Z, &c., tocatch the straw. Upon the said cylinder and much inclined to itssurface, are longitudinal ledges 0 0 0, &c., running its whole length,to receive any grain that may be brought over in the straw.

O is another cylinder, occupying an inclined position, to, and in therear of N, and for the like purpose, (of removing the straw,) butdiffering materially in its internal construction.

p p, &c., are teeth to catch the straw, attached to a stationary rod, oraxle 7c in Fig. 3, which is cranked at both ends within the cylinder toproject the teeth p p on one side, beyond the surface, while on theother side, they extend only to it.

P, is a fan under the thresher, to blow out the chaff. I

h is a concave cog wheel attached to the felly of B b, and meshes into apinion Q.

R, is a large concave cog wheel, upon the axle of 2, meshing into apinion 1", upon the axle of the thresher, and into a pinion 2',

upon the axle of the fan.

Q g are pulleys, upon the axle of Q and R, and between them, aroundwhich bands, d, d, pass to pulleys 11/, upon the axle of N, and to T,upon the axle of O.

U, is a large box under the fan, to receive the grain. u, a sliding gatefrom which the grain may be discharged.

V, is a lever upon a fulcrum between C, and D, having rods 7) '0,attached to'sliding blocks in which the axle of B b, works, and by meansof which the concave cog wheel B b, may be thrown in, and out of gear atpleasure. X X caps (not shown in the drawings,) to cover the cylinders,which complete the machine a traveling thresher.

The operation of the traveling thresher, consists in attaching horses asto a common wagon, and by giving motion, the wheel B b, having theconcave cog Wheel h, and, meshing into the pinion Q, gives motion to R,which meshing into the pinions, r, and 2' gives motion to the thresher,and fan. Upon the axle of Q and R, the pulleys g 9, have cords oZ, d,which pass around the pulleys,

N and T, by which the cylinders N andO, are put in motion. By therevolution of the cylinder N, the pieces 6, e, 620., containing, theteeth, n n, &c., and sliding in grooves to and from the center, fall tothe bottom of the groove alternately, as each row comes under thecenter, by which the teeth are projected, which project-ion they retainuntil broughtabove the center, they then alternately retire to thesurface. In the cylinder 0, the teeth revolve upon a cranked axle 70. Bythe revolution of 0, they are carried around, and the crank throwing theaxle out of the center, the teeth are made to project in front andretire as they pass around with the cylinder.

Fig. 2 is a view of the machinery necessary to constitute it, astationary thresher, in which W \V, are strong timbers fitted into eachother and crossing at right. angles to be secured to the ground bystakes.

.V, is a vertical axle fitted and secured into the center of W, WV, uponwhich the wheel B b, is to revolve horizontally.

X and Y, are two beveled wheels of unequal size, X (the larger) having avertical axle, upon the top of which the pinion Q, of the travelingthresher, is to be placed into which it, of the wheel B b, meshes.

.S is a rod, connecting the axles of Y and of Q, and R, in Fig. 1.

g, is a brace secured at each end to keep the axle of X, in a properposit-ion.

G is a shaft or lever (or any number necessary) to be attached to B b,to which a horse or horses are to be hitched.

Fig. 8, is a view of the interior construction of O.

p p, &c., are teeth attached to the stationary rod, or axle is, crankedat both ends within the cylinder.

8, is a journal secured to one end of O by screws 6, t, &c., upon whichit turns, and hollow within, in which one end of 7c rests, While theother end of O revolves upon is, as a journal.

Fig. 4, exhibits an end view of N, show: ing the grooves in which 6,&c., slide.

Fig. 5, shows the axle of B b, when used as a traveling thresher.

The operation of the stationary thresher, is performed by attaching ahorse or horses to the shaft or shafts G, and giving motion, the wheelX, meshes into Y, which being connected with the axles of Q, and R, bythe rod S, gives motion to all the parts,as heretofore described in thetraveling thresher.

\Vhat we claim as our invention, and desire to secure by Letters Patentin the within described machine is The operation of the teeth in thecylinder N, for the purpose of removing the straw from the drum, eachrow by its own gravity sliding in the grooves, project the teeth farenough to catch the straw, which by its revolution is brought up overthe cylinder, when they retire by their gravity and the strawis thrownfrom the machine.
